Definitions

  • the present invention relates to a method for producing a lightweight board with at least one fastening element and a lightweight board with the features of the preamble of claim 8.
  • the DE 10 2005 060 528 discloses a method for securing an insert body in a lightweight panel, wherein the insert body is inserted into a recess and then fused with a cover layer.
  • the insert body made of thermoplastic material and is then at least partially plasticized. Bonding by heating the insert body is problematic, however, because the contact surface is usually dirty on the cover layer during insertion of the recess. If the insert body liquefied too much, it can lead to deformations that adversely affect the mechanical stability of the compound.
  • the WO 2006/097518 discloses a method of attaching a hardware element to a wood material element, wherein the hardware element is coated with an adhesive. Subsequently, the fitting element is then brought into contact with the wood-based material element and by heating the adhesive and then curing, bonding between the fitting element and the wood-based material element is then brought about.
  • the disadvantage here is that the coating of the fitting element is relatively expensive. Especially with smaller fitting parts, such as dowels, the additional coating of a contact surface of the fitting part increases the costs considerably. In addition, the coating can be easily damaged when handling the fittings.
  • connection insert for lightweight panels, in which a Klebstoffzu Crystallar is formed.
  • the use of liquid adhesive for bonding a connection insert is possible, but also comparatively expensive in the process design.
  • an upper and a lower cover layer is first wetted with a liquefiable under heat adhesive and then glued with an intermediate layer.
  • the adhesive can be applied as a film, granules or in powder form on both cover layers under the action of heat, in order then to be glued to the intermediate layer to a lightweight board.
  • a recess in the upper cover layer and the intermediate layer is introduced and a fastener inserted into the recess, wherein a lower contact surface of the fastener rests against the adhesive coated lower cover layer.
  • the adhesive is reheated in the region of the lower contact surface of the fastener and the fastener glued to the lower cover layer.
  • the adhesive for fastening the cover layer to the intermediate layer can also be used at the same time in order to glue the at least one fastening element to the contact surface.
  • a prior coating of the fastener is not necessary and also the introduction of additional adhesive through adhesive channels can be omitted. It is only intended to apply the adhesive to the lower and / or upper cover layer in a sufficient thickness.
  • the fastening element can optionally be glued to the upper or the lower cover layer with the contact surface.
  • the lightweight board is cut before the introduction of the recess. Because the bonding of the outer layers with the intermediate layer can be done in a continuous process, wherein large plates or a web is produced, which is then cut first for further processing. Then, the introduction of the recess can take place at a predetermined position of a cut plate.
  • the heating of the adhesive in the region of the lower contact surface of the fastening element is preferably carried out by an electromagnetic field.
  • the heating of the adhesive can be carried out with exact position in order to largely avoid heat in the adjacent area.
  • the heating by an electromagnetic field can be done relatively quickly, which reduces the cycle time.
  • the fastening element is formed profiled on the underside and rotated after insertion into the recess.
  • the impurities produced during the production of the recess can be pushed radially outward, so that at least part of the contact surface bears against the initially dry and cured adhesive layer. This improves the bonding result during the subsequent heating and liquefying of the adhesive.
  • the adhesive is preferably applied when wetting the lower or upper cover layer to a thickness of more than 0.1 mm, in particular more than 0.2 mm. As a result, the adhesive is present in sufficient thickness to glue both the intermediate layer and then at least one fastening element.
  • annular contact area between the upper cover layer and the fastening element can also be heated.
  • the annular area heats up with the adhesive arranged there and can likewise cause a bonding between the fastening element and the upper cover layer.
  • the lightweight board For a particularly effective production of the lightweight board several fasteners are glued to the lower cover layer in one operation.
  • the gluing can also take place in a continuous process in which corresponding heaters are activated at the recesses.
  • the at least one fastening element is glued by means of the adhesive layer with the lower cover layer, with which the intermediate layer is glued.
  • the fastening element and / or the cover layer need not be wetted with an additional adhesive layer, which enables effective production.
  • the adhesive can be heated and liquefied by an electromagnetic field.
  • the adhesive may include electrically conductive particles, such as metal particles, which may be heated by magnetic induction. So that the fastening element can be bonded to the cover layer with sufficient strength, the adhesive is preferably applied with a layer thickness of more than 0.1 mm.
  • the fastening element is preferably designed as a plastic anchor, which is glued into a lightweight board for the furniture sector.
  • the intermediate layer can be formed as a honeycomb cardboard with a plurality of cavities, so that even large volumes of lightweight board can be made with low weight.
  • a lightweight board 1 comprises an upper cover layer 2 and a lower cover layer 3, which may be formed, for example, as wood-based panels, cardboard or plastic sheets. Between the upper cover layer 2 and the lower cover layer 3, an intermediate layer 4 is arranged, which may be, for example, a paper honeycomb construction with numerous cavities.
  • the upper cover layer 2 and the lower cover layer 3 are wetted on one side with a layer 5 of adhesive, at least in the region in which an adhesion to the intermediate layer 4 is to take place ( FIG. 2A ).
  • the adhesive may be thermoplastic hot melt adhesive that heats and cures several times without losing its adhesive power. The heating can be done depending on the composition of the adhesive via electrical or electromagnetic fields or via microwave radiation. An application of the adhesive 5 and 5 'as granules, powder form is also conceivable.
  • the layer 5 zw. 5 'of adhesive can be applied in a continuous process on the outer layers 2 and 3, in which case an adhesion of the outer layers 2 and 3 takes place with the intermediate layer 4.
  • the adhesive then cures on the cover layers 2 and 3 and the lightweight board 1 thus produced can then be stored temporarily and be cut. It is also possible, after the application of adhesive 5 or 5 'on the outer layers 2 and 3, first to cure the adhesive and then at a later time to heat the layer 5 or 5' of adhesive and to bond with the intermediate layer 4.
  • a lightweight panel 1 thus produced is in FIG. 3 shown. This can now be cut to the desired size, whereby a border-sided trimming can be done. To connect the lightweight panel 1 with other parts, one or more fasteners 9 are set.
  • FIG. 4 a recess 6 recessed in the lightweight panel 1, which is formed by the upper cover layer 2 and the intermediate layer 4 up to a bottom surface 7 fixed to the lower cover layer 3, wherein the layer 5 of adhesive was not mechanically removed during production of the recess 6.
  • the fastening element 9 has a lower contact surface 10 which is positioned on the bottom surface 7.
  • the fastening element 9 is designed as a cylindrical dowel, which has an upper edge region 11. When inserting the fastening element 9, the ribs are applied to an annular opening 8 in the upper cover layer 2.
  • FIG. 5 After inserting the fastener 9 is now in FIG. 5 reached shown position.
  • a device 13 for generating an electromagnetic field is provided, by means of which the adhesive 5 or 5 'is heated on the cover layer 3.
  • the adhesive 5 or 5 ' liquefies and, during the subsequent cooling and curing, can produce a bond between the fastening element 9 and the cover layer 3.
  • the fastening element 9 is designed as a plastic dowel with a lower contact surface 10, which has a profiling in the form of corrugated fins or ribs 13. By profiling on the contact surface 10th It is possible, after inserting the fastener 9 to rotate this to push any dirt on the bottom surface 7 of the recess 6 radially outward and thus improve the joining result between the fastener 9 and the cover layer 3.
  • the fastening element 9 has a bore 12 or channel for fixing fastening means, such as bolts or clamping elements.
  • a plurality of fastening elements 9 can also be adhesively bonded to the lower and / or upper cover layer 2 or 3 at the same time in one operation. It is possible, instead of the plastic dowel shown to glue other fasteners accordingly.
